BOX.

Application mea February a, 1925. serial No.e,413.

The present invention relates to box con struction and particularly to acarton or box having a spout produced by a novel articulation of thematerial from which the topv of the box is formed. Among the objectsofthe invention are the following: v

The provision of a box having a self contained spout; y

The adaptation to box construction of a blank so articulated as toproduce a spout adapted to serve also as .a closure member;

An unique blank and novel means for folding such blank to provide a box,and a closure member and spout therefor;

An advantageous design for spouted box construction /making unnecessarythe use of more material than for conventional structures; and

An improved box or carton Yformed from a single blank of material andincluding as a part thereof, 'a spout adapted to provide a' closuremember. l

These, and such other objects as may hereinafter appear, are attained bythe novel construction, combination, and arrangement of the severalelements comprising the box structures made in accord-with the inventiondisclosed in the accompanying drawing, hereby made a part of thisapplication, and in which: 1

Figure 1 is a fragmentary perspective view of the top of a box made`under the teachings of the invention, the foldable spout being in openposition;

Figure 2 is a top view of the same box with the spout folded to providea closure member;

Figure 3 is a fragmentary plan view of the blank used to form the boxillustrated in Fi ures 1 and 2;

igure 4 is a fragmentary perspective view of the top of a second boxembodying the invention;

'Figure 5 is a top view of the second box embodying the invention inclosed position;

Figure 6 is a fragmentary plan view of the upper end of a blank employedfor forming the box illustrated in Figures 4 and 5;

Figure 7 is a fragmentary perspective view of the. top of the third boxembodying the invention;

Figure 8vis a top view of the same box with the spout folded to providea closure member; and

Figure 9 is a fragmentary plan view of the upperlend of a blank employedfor formingthe box illustrated in Figures 7 and 8.

Like reference characters are used to des- .ignate similar parts in thedrawing and in the ensuing description. n Figure 1 illustrates a boxhaving sides 10, ends 11, and a top 12, manufactured partly after theprocesses common to the art of boxmaking, and of the materials usuallyemployed in box and carton production, the in' vention residing in theparts of the top 12 employed to form a spout 13 about an aperture oropening 14 in top 12, and which spout, in Figure 2, is shown folded toprovide a closure member for said aperture, 14. In the plan view shownin Figure 3, the die-cuts and' scores required upon oneend of a blank toform the box illustrated in Figures 1 and 2, are disclosed. Theundisclosedv end of the blank illustrated in Figure 3 is die-cut andscored in any of'the usual manners to provide a conventional closed endfor the carton described here.

From left to right, Figure 3 discloses an end 11 having an extension orap15 rec-- tangular in form and not diil'erent from the usual box endflap; an adjacent side 10 provided with an extension 16 separated by adie-cut from the material of/flap 15 in a.4

sion 16 to the n1L rgin at the opposite side ofend 11; a side 1 havingan extension of flap 18 coextensive, t erewith and containing a rounded(but substantially triangular) opening (forming the aperture 14)arranged therein, generallyl off center so that the material removedfrom flap 18 is taken from a point away fromlthe margin edge of side 10and extends upwardly tothe outer edgeof extension 18; and an extensionsection 19 upon the left hand,` margin of end 11 and c oextensivetherewith. The extension 19 could be placed with equal facility at theopposite end of the blank illustrated and upon the side 10. y/

f' Thus cut, theblank in reality presents but three extension portions,15, 18 and 16 and 17 which are /inte ral, a score 20 marking the pointof, the ivision betweenIo part 16, the extension portion of one side 10,and part 17, the extension portion on the adjacent end 11.

In addition to the score 20, the part 16 is die-cut on a line 21substantially at -a ninety degree (90) 'angle to the external obliguemargin of section 17 such cut 21 extending about two-thirds of thedistance to the juncture of side 10 and its extension 16.

From the internalextremity of score 20, two scores, 22 and 23, radiateinto extension 16, the first 22 being perpendicular to the cut 21, andthe other 23 lextending to the internal extremity of said cut'21. rl'Lhematerial of extension 16 adjacent the outer end of line 21 maybe cut inthe form, as shown or rounded, to facilitate the production of neatarticulations and cleanly gluing operations. A

In section 17, a score 24 at a ninety degree angle to the oblique outermargin of said extension is run to the point'of coincidence of scores20, 22, and 23, the score 24 being substantiallyv parallel to the cut21, in extension 16.

A score 25 extends from one end of the blank to the opposite other endthereof, separating the sides l0 and the ends 11 from the flaps orextensions 15, 16, 17 and 18. Additional parallel scores 26, 27, 28 and29, perpendicular to score l25, separate the sides and ends, 10 and 11,and the end 11 and extension 19. 5

When cut and scored as herein indicated, the blank, partly shown inFigure 3,` is ready to be folded. When folded upon scores 26,127, 28 and29 and the flap 19' glued to the opposite side 10, the bottom of the boxmay be closed by gluing the severalflaps at that end, the operation ofclosin the bottom being conventional to the box-ma 'ng art. f

When thetop is to be closed, flap 15 is first turned in, flap 18 isfolded thereover and glued, and then flap 16 is folded over extension 18and glued' thereto, the glued section not extend-ing beyond the cut 21or the score 23.

' `A double rimmed aperture 14 is thus formed, the edge of the openingin iap 18 forming the projecting internal shoulder in said aperture, andthe material of flap 16, on one side of cut 21, the external or largersection of the opening 14. v The lgluing 'of' iap 16 'upon flap 18automatica y vforms the spout 13 shown in Figure 1, said spout havingfour sections-'to give it flexibility and adapting it to ready fold ing.The spout sections are that portionA of material between scores 25and/'24, that or-V tion of material between scores 24 an 20, thatportion of material between scores 20 and 22, and the small section ofmaterial between scores 22 and 23. 7 l

To close the aperture 14 and vgive tothe carton the contour disclosed inFigurel 2,

the last mentioned two sections are flattened out parallel with top 12to cover aperture 14,

leaving projecting upwardly the two sections of the material fallingbetween scores 25 and 24, and between scores 24 and 20 both of the samegeneral size and shape. )These are conjointly folded inwardl upon top 12over the sectlons of material etween scores l22 andv 20. Said foldeddownsectionsv are held down upon top 12 b an adhesive strip or by a papercover w ich is frequently pulled or wrap ed over cartons to insuresanitation and t e preservationof the contents thereof. To open thecarton, the secr.

and ends of the box are -formed in the usual manner. The sides aredesignated 30 and the endsp31, and upon one side 30 is a short extension31a for gluing the box longitudinally. A top is formed by aninterlocking of extensions or flaps upon said sides 30 and ends 31 justas in the previously described form of theinvention. One of said sides30 has an extension 32 coextensive therewith and having at its outermargin a cutout central rtion 33 shown in full lines in Figure 4 anin'Figui-e 6. Each of ends 31 is provided with an extension 34, one sideof which is diecut"at the outer side to separate it from the sheetmaterial from which the blank is cut. Said cuts are respectively acontinuation of the articulation between the side 30 carrying extension32 and the end 31, and the articulation between opposite end 31 and side30. The other edge ofthe flaps 34 'is integral with a flap 35coextensive with the second side 30, the outer edge of flap 35 beingserrated as indicated in provide a lip35, l

Each Hap 34`has a score;36 extending from the extreme outer cornerthereof obliquely to the oppositely inside corner adjacent side 30. woparallel scores 37 separate iaps 34 from ap 35. A C v Upon flap 35 aretwo diagonal scores 38 which extend from the intersection of scores 36and 37 toward the end of lip 35*l where Figure 5 to I material in theserrated. edge Vof flap 35,

such removal of material vdetermining scores 38 before such intersectionoccurs. The serrations in flap 35 provide in addition to the central lip35 for the ready manufacture of the box, facilitating the articulationof the material and operation ofthe spout. A continuous score 39separates the sides 30 and ends 31 from the extensions 33, 34 and 35,and parallel scores 40, 41, 42, and 43 separate said sides and ends andend 31 and extension 31a.

After` -the' box is folded longitudinally land glued atextension 31* tothe opposite side 30, the flap 32 is turned inwardly.v

Upon flap 32, are glued so much of the flaps 34 as is bounded by thescores 36 and 39. A spout and closure member is formed of the remainingunglued material of flaps 34 and by flap 35.. Such spout comprises fivesections of material, the two remaining and unglued sections of flaps 34bounded by scores 36' and 37, and the three sections of ap 35, separatedone from another by scores 38. Accordingly as to whether the ungluedsections of aps 34 rests upon the margin of fiap 32 about aperture 33'or are pulled upwardly from said flap 32, the five sections justreferred to are a closure member or a spout.

When used as a closure member the unglued sections of flaps 34 arepressed inwardly as above indicated, and the three sections of ap 35bent thereover the sections thereof between scores 37 and 38 fallingunder the section between scores 38. To open, the folded sections of ap35 are bent outwardly and separated, such separation concurrentlyraising the unglued portions of Haps 34. The aperture in the top of thebox through opening 33 in flap 32 is opened by spreading the sections 34and 35 to form a spout, and the contents of the box may then be removed.When the box is to be closed, the spout is folded over the opening 33 inthe manner hereinabove indicated. Before first used by a consumer,the\box is held tightly closed by an adhesive strip or paper coveradapted to compress the folded spout sections. t

In Figures 7, 8 and 9 the third form .of box embodyingthe invention isdisclosed. Reference should be had first to Figures 7 and 8 where a boxhaving sides 50, ends 51 and a top 52 is disclosed. -A foldingspout-like portion 53 is adapted to close an aperture 54 in top 52 whenin folded or closed position, as shown in Figure 8.

Reference should now be had to Figure 9. This is representative of avblank adapted to form the box disclosed in F igures 7 and 8. Readingfrom right to left the side50, the adjacent ends 51, the contiguous side50, and they second end 51 are shown. Upon said la t ,mentioned end -51is an extension p ortio 55. Suitable scores 56, 57 and 58 separate sides50 and end 51, and a score 59 is used to 'separate extension from theadjacent end 51.- All of the:

scores mentioned are parallel.

A horizontal score 60 provides a parallel margin for said -sides 50 andend 51. Again reading from the right to the left it will be noted thatthe side 50 is provided with an extension 61, the sides of extension 61being die-cut. The sides of extension 61 are parallel to the margins ofsides 50. In

the upper left lhand corners of extension 61 is a quadrant 62 separatedfrom the main body of extension 6l by a continuous series ofperforationsmaking it a simple matter to remove section 62 from extension 61 whensuch removal is desired.

Upon the adjacent end 51 are two extension portions, t-he material ofwhich when united would provide a single extension of substantially thesame width as the end 51.

The first of the extensions upon end 51 is designated 63, and comprisesa portion of material separated from .end 51 by the.

score 60, the left hand margin off the extension comprising an are of90o so that extension 63 has the general form of an L.

lThe second extension 64 upon the end 51 is equally disposed thereuponand upon the contiguous side 50. Such extension 64 com-A prises a halfcircle in which two scores 65 and 66 radiate from the intersection ofscore 57 and score 60. Score 65 is in reality a continuation of score 57while score 66 is disposed intermediate score 65 and'score 60 and isequidistant therefrom.

Upon the side 50 is an extension 67. This extension is separated fromside 50 by the score 6() and extends from score 58 to the die-cut usedto form extension 64. The adjacent ends of sections 63 and 67 areseparated by a die-eut 68. Upon the left hand end 51 is the usual andcustomary flap or extension 69, which is generally rectangular inconfiguration.

After the blank illustrated in Figure 9 is die-cut and scored, the sides50 and ends 51 are folded and glued together at extension 55. The flapsupon the bottom end of the box, such flaps not being shown, are of theusual form, and are used to close the box at its bottom. v

Extension 69 is folded'inwardly. Extension 63 is next folded down.Extension 67 is then glued over extensions 69 and 63. The arcuate diecutwhichA separates section67 from extension 64 exactly coincide with thatportion of the same die-cut which separates section 63 from saidextension 64. An opening having an internal arcuate margin heretoforedesignated 54 is thus formed.

The material of extension 64 is folded with that portion between thescores 60 `and 66 lowermost, with that portion bet-Ween the scores 66and 65disposed over the first mentioned section, and the section betweenthe score 60 and score 65 uppermost. This last mentioned section isfolded in the same plane as section 67. When so folded 'the -section 61having the detachable portion 62 tension portion 61 by running a knifeorv the finger nail along the separating perforations which divideextension 61 romsection 62. Section 62 is pulledl outwardlyand as it isdisposed upon, glued to and of the same size 'as the sectionof extension64 between scores 60 and 65, an outward pull upon section 62 causes thespout, heretofore designated 53, to be formed. The material of suchspout comprises the three sections of extension 64. To close the boxafter the first opening, it is only necessary to press downwardly uponsection 62 which causes the material of section 64 to fold in the mannerhereinabove indicated, the roughened edges intermediate 4 extension 61and section 62 ordinarily being sufficient to hold the spout in closedposition.

I claim: l

1. Ina container, having an opening, a closure comprising a single sheetyof material constituting extensions of the Walls of said container,said extensions being creased in parallelism with -the divisions in theWalls of said container and at an angle of fortyfive degrees therefromto define a substantially enclosed converging spout, said spout beingfoldable to assume a position in a flat plane over said opening to serveas a closure for said container.
